No More Learning

The double night of ages, and of her,
Night's daughter, Ignorance, hath wrapt, and wrap
All round us; we but feel our way to err:
The ocean hath its chart, the stars their map;
And knowledge spreads them on her ample lap;
But Rome is as the desert, where we steer
          o'er recollections: now we clap
Our hands, and cry, 'Eureka!
